{IMPROVEMENT IN GAS HEATING APPARATUS.

G Specification forming part of Letters Patent No. 71,002, dated November 19, 1867.

To all whom it may concern:

Be it known that I, DAVID GREENE HAs- KINS ,of Cambridge, in the county of Middlesex andState of Massachusetts, have invented a new and Improved Device for Producing a Heating Flame Generated from Gas, Vapor, Oil, or other Burning-Fluid, of which the following'is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of the same, in which- Figure 1 represents a section of my device as applied to a gas or vapor burner, with a mixing-chamber for the air and gas attached. Fig. 2 is the same applied to a common lamp in which a wick is used. Fig. 3 is a top view of the'same. Fig. 4 is a partial transverse horizontal section, and Fig. 5 represents a device or apparatus for supplying air to the burners.

Similar letters indicate like parts in the several figures.

The object of my invention is to produce a device which may be readily applied to a gas burner or lamp of any description in which volatile or other oils or fluids are used, for the purpose of obtaining the greatest possible amount of heat either for cooking or heating; and the invention consists in the attachment to a burner or tube emitting gas or vapor, or to an oil or fluid burning lamp of any description, of an air-chamber, into and from which is forced a supply of air to mingle with such gas or vapor or with the flame of the lamp, in combination with a perforated tube and an air-supplying apparatus.

Referring to the drawings, A in the several figures represents an air-chamber of a conical form, constructed with an outer casing, a, and an inner casing, b, leaving a space between the two. The said chamber is closed at the bottom, and contracted at the upper portion, leavin g a small opening all around for the passage of the air to the flame. To the upper end of the inner casing, b, is attached a circular plate or ring, 4, and to the inner edges of this plate or ring is attached a perforated tube or pipe, B, extending downward a short distance below the casing A, as shown in Figs. 1 and 2. This tube is open at its upper and lower ends, and is designed to be placed or fitted over a burner Where gas or vapor is burned, or over a. lamp Where awick is employed. To the outer side of the casing A is attached a pipe, 17, which communicates with an air-reservoir, It, placed in any convenient situation, from which air is supplied to the chamber A.

Figure 1 represents my device attached to a burner where gas or volatilized oil is used. D represents a metal tube fitted over or upon the upper opening of chamber A, so that the air will pass from the chamber into the said tube and mingle freely with the gas or vapor from theburner. Extendinglongitudinallythrough the tube D is a rod, E, on the lower end of which is an inverted cone, k, which rests upon a cross-piece, e, and serves to deflect the gas or vapor as it arises. On the upper end of the rod is a button or plate, 0, placed on a level with the upper end of the chimney, and of a diameter sufficient to leave a small space or opening for the flame between its edge and the top of the tube D. Upon the the rod E is a se ries of deflectors, which serve to deflect the gases or vapor'in their upward course and cause them to mingle freely with the air from chamber A.

Fig. 2 represents my device as applied to a lamp in which the flame proceeds directly from the wick, and which is so arranged that the air from the chamber A will come in contact with the flame above the wick. The upper portion, g, forms a cap, which may be provided with an opening to conform to the shape of the wick used. The chamber A may be constructed of any form other than conical, if required, for adaptation to lamps or burners ofvarious forms, such as cylindrical, oval, 860.

Fig. 5 represents an apparatus for forcing air to the ohamberA and burners. It is shown as composed of a flexible portion, R, attached to rigid top and bottom pieces, S S, the upper portion moving between uprights, which guide and retain it in a level position. By raising the upper portion the reservoir will be filled with air, that enters through a properly-arranged valve, and as the upper portion descends the air will be forced out through the the pipe 10 to chamber A.

Instead of the above-described apparatus a fan-wheel or other suitable air-impelling device may be employed, which may be put in motion by means of a spring and clock-work or otherwise. The said reservoir or air-supplyin g apparatus may be placed in the cellar or other place at a distance from the chamber A, so as to supply, by means of conducting tubes, air to chambers in several rooms at the same time. The chamber A may be applied to any burner, either in connection with a cooking-stove or heating apparatus. It may also be attached to a gas-carburetor to force the vapor arising from the fluid to be carbureted to the burner. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of an air-chamber, A, ccnstructed, as described, with the ring r, the perforated tube B, and the air-supplying ap- DAVID GREENE HASKINS.
